Carbon Dots as Bioactive Antifungal Nanomaterials

Area of Science:

• Materials Science
• Mycology
• Nanotechnology

Background:

• Opportunistic fungal infections pose a significant global health threat, exacerbated by antimicrobial resistance.
• Existing antifungal drugs face challenges due to emerging resistance mechanisms in fungi.
• Nanomaterials, particularly carbon dots (CDs), are being explored for their biocidal properties.

Purpose of the Study:

• To provide an overview of recent advances in synthesizing carbon dots (CDs) with antifungal activity.
• To explore the potential of CDs as novel agents against infective fungi and drug resistance.

Main Methods:

• Review of carbon dot synthesis and characterization relevant to antifungal applications.
• Analysis of antifungal mechanisms of CDs against various fungal species.
• Evaluation of CDs, drug-loaded CDs, and CD-incorporated packaging systems.

Main Results:

• Carbon dots exhibit promising biocidal activity against fungi.
• CDs can be loaded with antimicrobial drugs to enhance efficacy.
• CDs show potential as fluorescent nano-trackers for bioimaging fungal infections.

Conclusions:

• Carbon dots represent a novel class of antifungal agents with tuneable properties.
• CDs offer potential solutions for combating drug-resistant fungal infections.
• Further research into CDs for antifungal applications and bioimaging is warranted.
